Application filed August 20, 1917. Serial No. 18*?,207.

To @ZZ whom t may concern Be it known that l, ALBERT D. Gnovnn, a citizen oi the United States, and a resident ot New York city, in the county of New York and State of New York, have invented certain new and useful improvements in Coin-Testing Devices for Coin- Controlled Machines, of which the followis a specification.

The object of my invention is to provide a coin-testing device for use in coin-conti'olled machines for testing the deposited check as to hardness. That is to say, when an improper check is deposited, of a material having a less degree of hardness than a proper coin, the check is prevented from passing into the machine, but may be withdrawn from the coin-entrance slot.

In the accompanying drawings, which show a. preferred embodiment of my invention, I

Figure l is a view in elevation of a portion or' a coin-controlled machine provided with my check is locked against movement into the machine; n

Fig. 2 is a section approximately on line 9F-2 orp Fig. l, looking in the direction of the arrows;

Fig. 3 is a cross-section approximately on line 3-3 or' Fig. l looking in the direction or the arrows; and

F ig. 4 is a view similar to Fig'. l, showing how a good coin is allowed to pass into the machine.

The operative parts of my mechanism are mounted on any suitable support, such as the plate l, which is adapted to be mounted in any suitable coin-controlled machine. For the sake of illustration, l have shown the plate l secured to the front wall of a casing M. As the construction of the casing and the delivery mechanism contained therein form no part or my present invention, I have not deemed it necessary to show more of the machine than a portion of the casing M. The supporting plate l is provided with a coin-passage 2, in which operates the coin-carrier 3. This coin-carrier is in the present instance shown in the form of a flat disk provided with semi-circular recesses l adapted to receive the deposited check or coin. The coin-carrier 3 is connected with any suitable member on the outside of the machine, such as a knob 5.

On the pin or studv 6 ci the plate l is invention, showing' how softV pivoted the coin-testing pawl 7, having a pointed end 8. The pawl 7 hangs normally in such position that the pointed end 8 eX- tends into the path of the coin as it is carried through the coin-passage 2 by the coincairier 3. if the deposited check is a proper coin`I the pointed end 8 will ride over the hard edge oi the coin, as shown in Fio'. 4, where the coin is indicated atY C. Y ontinued rotation of the coin-carrier will carry the coin C past the pawl '7, depress the spring-pressed stop 9, and then engage the pin l0 of a suitable operating member ll. The member ll may be of any form or construction and may have any desired function. For the sake of convenience, l have shown the coin-actuated member ll in the form of a lever pivoted to the front wall ot' the casing at l2. The spring-pressed slide 9, which has a beveled coin-engagingedge 13 and an abrupt shoulder let, is for the purpose of locking the coin and coin-carrier against return movement after the coin has been carried a sun'licient distance between the shoulder la and the pin l0. Also, if desired, the spring-pressed slide 9 may be so arranged that the upper end thereof engages the lower end l5 of the pawl 7, for yieldably holding the pawl approximately in the position shown in Fig. l during the normal position of the parts.

When a check or disk of soft material` such as lead, fiber, soft composition metal, etc-is inserted in the machine and the coin-carrier rotated, the pointed end 8 of the pawl 7 will bite into disk D and the latter will be jammed. or wedged between the coin-carrier and the opposite wall 16 of the clearly shown in Fig. l. lt should be noted IVIESNE ASSIGNMENTS, '10

coin-passage. This isv the edge of the soft that the pressure brought to bear against the disk D by attempted rotation or the coin-carrier is lnot borne by the pawl` 7, at least not to a large extent, but is taken up by the opposing wall 16 of the coin-passage. This is an important feature or" my invention, for in this way, the pawl 7may be oi" light and small construction, as it does not have to bear `any appreciable amount or strain. Also it will be seen from Fig. l that whatever thrust the pawl 7 has to bcar'is approximately in a line between the pivot 6 and the pointed end 8, which imparts to the pawl a maximum of resistance power.

The intercepted check is readily with simply rotating the coin-carrier 3 in the reverse direction. rllhs causes the check to be projected sufiiciently through the coin-slot to be removed, as will be clear from Fig. 1. rlhis removal of the intercepted checlr. is an important feature of my invention, as otherwise the machine would become clogged and put out of commission by the rst soft check that was deposited.

1t will be clear from ligs. 1 and d that the pointed end 8 of the pawl 7 is at all times out of engagement with the coin-can rier 3, and that the latter is normally free to rotate in opposite directions. 1n other words, the pawl 7 does not act as a stop for the dish 3 when the latter is rotated empty, and consequently there is no such wear on the pointed end d as would be the case if it engaged the coin-carrier to form a stop.

1n order to prevent dislrs of hard fiber from accidentally passing by the pointed end 8 of the pawl 7, under pressure of the coin-carrier, 1 provide the coin-seat d with teeth 17 which bite into the edge of the check and thereby positively prevent the same from slipping or whirling around its own anis when strong pressure is brought to bear on the coin-carrier by attempted turning of the knob 5.

1t will be seen from the yforegoing that l have provided an exceedingly simple and efficient device for intercepting soft checlrs. The pawl 7 occupies but little space and may be readily applied to vending machines of small dimensions, such as are used in theaters.Y 1t should be noted tirL t the cointesting pawl is at some distance froml the coin-entrance slot 18, so that it cannot easily be tampered with from the outside. j

Having thus described my invention, what 1 claim as new and desire to secure by etters Patent ofthe United States, is:

l. 1n a coin-controlled machine, a casing Vprovided with a coin-entrance slot and a coinpassage leading therefrom, a rotatable disk provided with a recess for receiving the deposited coin and carrying the same through said pass/age, and a pivoted pawl having a pointed end ent-ending into said passage to enter the edge of a soft check in said coin dislr and cause said checlzf` to be jammed between the coin disk and the opposite wall of said passage, said coin dish being reversely rotatable to bring the intercepted `check back through the coin-cir trance slot, said pawl riding over the hard edge of a proper coin toallow the same to be carried into the machine.
